I'm somewhat new to supabase auth and I'm struggling to find anything on this in the documentation, but can you use the signIn method in an API or does it have to be in a web client? I'm working on creating a full-stack app that I'd like to be able to use postman or the restClient for VS Code and I don't really see a way to do do that with supabase auth unless you can authenticate in the API... it kind of seems to rely on having an active webpage though.

The webclients just make API calls to various endpoints including auth(gotrue). Some of them also deal with token refresh issues. So for signin you use the supabase/gotrue API https://github.com/supabase/gotrue#endpoints

Thanks 🙂 looking through it now.
